Is it possible to hide navigation bar on e.g. tablets in activity, so it does not appear when user is clicking on the screen?
I want it to appear only when user is swiping from bottom to middle of the screen, just like in e.g. Real Racing 3.
When I use:
myView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Unfortunetly navigation bar is hidden, but when user is clicking, it appears again. I want it to work only with this swipe gesture. How it can be achieved?
This is a platform behavior. Apps do not have the sort of control of the navigation bar that you are looking for, and for good reason. All it takes is one app not implementing a way to show the nav bar and the user is stuck. You will have to design your app with the platform's behavior in mind.

i want to hide everything in Navigation bar except back button (rooted tablet) , i used to hide the Navigation bar completely (to restrict users access other applications and device settings) but the customers didn't like it because when users open PDF files or videos they forced to use physical back button to back to my application, so the only way is to customize the Navigation bar to show back button only , any suggestions?
EDIT : its possible to create my own Navigation bar like full!screen?
Sounds like you want to do a kiosk tablet. A lightly customized rom with a navigation bar having only the back button might be what you want to do..
I want to dismiss bottom Navigation bar for one particular screen.
I tried using
setSystemUiVisibility(HorizontalScrollView.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
I have put this in Onscroll of my scrollView, ontouch of my views.
but the issue is its comes back and the screen gets resize.
Any suggestions by which I can completely remove the NAVIGATION BAR.
Check out SYSTEM_UI_FLAG_HIDE_NAVIGATION, this flag hides the navigation bar until the user interacts with the device. It's new in Android 4.0. You can enable this flag for example like this:
getWindow().getDecorView()
.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Note that the navigation won't disappear again automatically, you have to set it every time after the user interacted with the device.
Alternatively you can make the navigation less obtrusive by using SYSTEM_UI_FLAG_LOW_PROFILE, this changes the buttons into small dots (e.g. like the camera app).
I am writing an App using MonoDroid and for some reason I cannot pull down the notification bar from the top of the screen. I am thinking this has to do with my layout, but I am not sure. I also notice that when my App is running I do not have the bar at the top showing the battery, time, signal strength, etc.
So, my question is, what do I need to do to allow the user to pull the notification bar down? And how to show the info at the top of the screen?
I suspect you have done something to make your app appear in "Full Screen" mode (this will turn the home, menu and back buttons on the bottom of the screen to dots, and hide the navigation bar.
I believe this is called "lights out mode". Here is one SO question asking how to turn it on (maybe it will help you turn it off as well): Hide ICS back home task switcher buttons
Maybe your theme is
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" ?
It hides the notification bar. Change to a non-fullscreen theme to make the the notification bar visible.
Im developing an android 3.0 + app.
I want to remove the status bar at the BOTTOM of the screen, the one with the android nav and time in. I've managed to remove the top bar already.
Anyone know how it's done?
Thanks

This is not supported. The user needs the system bar in order to navigate the device (e.g., press HOME).
I am currently planning the honeycomb update for my app and i am wondering how to use the Action Bar correctly. My first question is if it is possible to hide the App-Icon and Title from the Action Bar.
And is there any kind of Design guidline for the Honeycomb-UI yet?
Yes, you can hide the app icon and title. You can also replace the app icon with a wider logo image for your activity.
The app icon/logo at the left is collectively treated as a "home" affordance. You can optionally ask the system to display it as "up." When tapped, this should take the user either to a home/landing page for your app or one level up in the app's navigation hierarchy, respectively.
This complements the system back button by providing a consistent way for the user to move around your app when the history associated with the back button might be complex. (For example, the user might have been deep-linked into your app through a notification or an intent from another application.) By using this pattern your app won't need to hijack the normal behavior of the back button in special cases for convenience.
The action bar does double duty in the form of action modes. The two APIs are orthogonal but the resulting UI occupies the same screen real estate. An action mode presents a set of contextually relevant options to the user as a customized action bar. For example, a user might select several items from a list at a time. The app might present an action mode to let the user take a bulk action on the set of all selected items such as delete or share.
Action modes are a great way to present contextual actions that doesn't stop the user from interacting with the rest of the UI the way that popup menus do.
Design guidelines will hopefully be published "soon." :)
